New study finds dogs are more than twice as smart as cats

New study finds dogs are more than twice as smart as cats

You've always known it to be true but you never had proof, until now: A new study has determined that dogs are in fact more intelligent than cats. Neurons are cells that process information.

It's a pretty significant difference, this study did not prove the fact that the more neurons, more brain.

Neurons are associated with thinking, planning and complex behavior.

The findings showed that while dogs have about 530 million cortical neurons, cats have 250 million.

For the study, described in the journal Frontiers in Neuroanatomy, the team analysed the brains of one or two specimens from each of eight carnivoran species: ferret, mongoose, raccoon, cat, dog, hyena, lion and brown bear to see how the numbers of neurons in their brains relate to the size of their brains. Among our closest cousins, orangutans and gorillas have about eight to nine billion neurons, while chimpanzees have about six to seven billion neurons.

When they looked at a 64-pound golden retriever, the count was even higher: 627 million neurons.

No reported deaths due to dengue vaccine: Sanofi
The analysis confirmed Dengvaxia provides persistent protective benefit in those who had prior infection, Sanofi said. Those who had been vaccinated "are being followed up for adverse effects", he said.

They might chew your shoes, occasionally pee on the rug, or snarf down your entire dinner the minute you turn your head, but it turns out your family dog is measurably smarter than your cat.

Of course, such an arbitrary measurement of the brain is not an objective metric of such a complex trait as intelligence.

Now, after counting the number of neurons in the cerebral cortex of a range of carnivores, there's finally something in the way of conclusive evidence about which animal has more capacity for intelligence, and it's dogs.

The research was done in the lab of Suzana Herculano-Houzel, an associate professor of psychology and biological sciences at Vanderbilt University. Bears, on the other hand, have brains ten times the size of a cat's, but around the same number of neurons.

Carnivorous animals were compared in the study, consisting of 280 species of mammals characterized by teeth and claws allowing them to eat animals.
